eclipse启动时报JDK is required错误

安装m2eclipse插件后，eclipse启动时红色字体报错“Eclipse is running in a JRE, but a JDK is required”。解决方法需在eclipse.ini文件中增加-vm参数。

eclipse.ini文件：
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810
